JOHN 'E. GAITLEY, OF ALBANY, NEW YORK, ASSIGNOR TO ALBANY-FOUNDRY COM-PANY, OF ALBANY, NEV] YORK, A CORPORATION.

STOVE.

T 0 all whom it may concern.

Be it known that I, JOHN E. GAITLEY, a citizen of the United States,residing at Van Rensselaer Island, in the city of Albany, in the countyof Albany and State of New York, have invented certain new and usefulImprovements in Stoves, of which the following is a specification.

My invention relates to stoves and ranges, and the object of myinvention is to provide a stove or range particularly adapted forburning coke, and to provide a means for heating the air used forassisting in combustion before it is brought in contact with the fuel,together with such other elements and combinations as are hereinaftermore particularly set forth and claimed. I accomplish these objects bymeans of the mechanism illustrated in the accompanying drawings, inwhich:

Figure l is a transverse section. Fig. 2 a longitudinal section. Fig. 3an inverse plan view of the bottom of the stove. Fig. 4L a perspectiveview of a range to which my invention is applied. Fig. 5 is a plan. Fig.6 a section along the line Z-Z on Fig. 5.

Similar letters refer to similar parts throughout the several views. I Ihave shown in the drawings a range provided with an air box, B, securedto or formed on the bottom, A, thereof, the air box having a portion, C,extending preferably from one side of the range to the other beneath theash pit, D. In the air box, B, I have a register, E, which may be openedor closed by means of the lever, F, provided with a suitable disk, G,having openings therethrough adapted to coincide with openings in theair box, and so arranged that the movement of the handle, F, from rightto left will open and close the register. The end of the lever, F, ispreferably right angled, as shown in Fig. 1, and protrudes through acurved opening, f, in the shelf, H, on the side of the stove or range.

Along the side of the stove within the ash pit I provide for theentrance of the air beneath the grate, d, for assisting combustion,which passes through the register, E, air boxes, B and C, through thetwo upright fiues on each side of the front of the stove formed by theprojections, J, J, secured to the top of the air box, 0, and the sides,K, K, of the range. To prevent ashes from passing into these fiues ateach end of said box I Specification of Letters Patent.

air in the box to pass out beneath the covers in the manner indicated byarrows in Fig. 1. The ash pit, D, is very similar to that of an ordinarystove, except that there is preferably no opening for the draft thereinex-' cept that provided as hereinbefore set forth, by means of the airboxes, B and C. For the purpose of removing the ashes I may place in thehearth, M, a suitable door, m. Above the grate, cl, in the fire box, N,the fuel, 6, is placed. The space over the oven, S, is separated intotwo compartments, 0 and Y, by means of a right angled partition, 9,which extends from the side of the stove near the chimney flue, P, to apoint-toward the longitudinal medial line of the space above the oven,and then extending to that end of the stove opposite the fire box. Insaid partition near its end opposite the fire box, I place a damper, Q,which when opened makes communication between the space, 0, and thespace, Y, whereby the gases, smoke and products of combustion in thefire box may pass through the space, 0, into the space, Y, and fromthence into the chimney flue, P. The damper, Q, may be raised or loweredby means of the rod, R, connected therewith and passing through the sideof the stove as shown in Figs. 1 and 5, the dotted lines in Fig. 1showing the position of the damper when it is partly opened, itspreferable position when the fire is starting, the full lines indicatingits closed position. When the damper is opened the gas and smoke willpass directly from the fire box into the space, 0, and from thence intothe space, Y, and out through the flue, P. When the damper is closed thesmoke and gas will pass into the space, 0, and then downward through thespace 0 into the space 0 around the partition, T, and upward into thespace, Y, and out through the flue, P, as indicated in Figs. 5 and 6 bythe arrows. The products of combustion, carrying the heat, pass from thefire box and through the space, 0, which in case of a range is over theoven, S, and toward the back of the stove where they pass downwardthrough the space 0' to the space 0 at the bottom of the oven, thencearound the flue partition, T, which is in the space 0 and O as shown inFig. 2.

The air entering the air box, B, is warmed by comin in contact with thebottom, A, of the stove, because of the warm air circulating within thespace, so that when it reaches the grate, (Z, it is hot and adds to theefficiency of the range, because none of the heat from the grate orburning fuel is taken away or retarded as is the case when cold air isbrought in contact therewith.

lflxcept when starting a fire and for a very few ioments thereafter thedamper, Q, will be closed and my stove will be substantially air tight,that is, there will enter no air except the heated air which isintensely hot and is delivered below the grate from the lines at theside of the range between the projections, J, J, and the walls, K, K, ofthe range in the form of a hot blast and which is controlled by thelever, F, and may when desired be entirely shut off.

Great dilliculty has heretofore been experienced in burning coke in astove. A coke tire is so hot that it quickly destroys an ordinary stoveand it burns so fast that it is not generally considered practical fordomestic use. I have found that if the air is heated, the fire may becontrolled to such an extent that the stove will not be burned out; thatan equable heat may be delivered and combustion maintained withoutattention all night.

My invention furnishes a stove in which a by-product, coke, may beburned successfully and thus a cheap fuel furnished those who cannotalford to pay for coal.

W hat I claim as my invention and desire to secure by Letters Patent,is:

1. A store adapted for burning coke or a like fuel, comprising a firebox; an air box placed on the bottom of the stove; orojections on thatportion of the air box extending beneath the fire box spaced from theside of the fire box, through which air from the air box may enter thestove; a register in the air box; a means for opening and closing theregister from the side of the stove; an oven spaced from the top bottomand end of the stove; a partition above the oven at the top of the stovedividing the space into two compartments; a chimney flue registeringwith one of said compartments, the fire box having free communicationwith the other of said compartments; a damper in said partition; apartition between the bottom of the oven and the bottom of the stove andbetween the end of the oven and the end of the stove forming a ductextending from that portion of the space at the top of the stovecommunicating directly with the lire box and a duct extend ing from thatportion of the space above the oven communicating directly with thechimney, substantially as described.

52. A stove adapted to be made substantially air tight, comprising afire box; an air box on the bottom of the stove communicating with thefire box beneath the fire; a means for controlling the passage of airthrough said air box into the stove; a chimney flue; an oven which isspaced from the top, end and bottom of the stove; a means for conductingthe heat from the fire box to the bottom of the stove above said airbox, comprising a duct formed l) a partition in the space between thetop of the oven and the top of the stove dividing the space into twocompartments, one of which communicates with the fire box and the otherwith the chimney flue; a damper in said partition; a partition extendingfrom the top to the bottom of the stove and along the bottom between thebottom and the oven, separating the space between the end and bottom ofthe stove and the oven into lateral compartments, one communicating withthe compartment at the top of the stove which is in direct communicationwith the fire box, the other with the compartment at the top of thestove in direct communication with the chimney flue, whereby thecirculation of hot air is, when the damper is closed, from the fire boxdown the end of the stove, across the bottom thereof, above the air box,around the partition and out through the chimney.

In testimony whereof I have affixed my signature in presence of twowitnesses.
